1 Claim.4 (01214-120) l My invention relates to incinerators, particularly the larger sizes,` used by factories, mills, packing establishments, 'motion picture studios and the like for burning large quantities of refuse and the principal object of` my invention is to provide simple, -eilicient and easily operated means for delivering Waste material to the charging door of the furnace and'which-latter, it will be understood in thelarger sizes of incinerators, l

is located aV considerable `distance above the ground or floor upon which said incinerator rests. A further object of my inventionis to provide simple and eiective means for preventing paper, leaves and other lightweight refuse from being blown away by the wind while discharging from the skip into' the charging door of the incinerawr.'

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, which will be hereinafter more fully described and claimed and illustrated in A the accompanying drawing in which:

Fig. 1 is a perspective view of an incinerator constructed in accordance with my invention.

Fig. 2 is agvertical longitudinal section taken on the line 2-2 of Fig. 1.

Fig. 3 is a cross section taken on the line 3-3 of Fig. 2.

Fig. 4 is detail section taken on the line 44 ofFig. 1.

Fig. 5 is an enlarged horizontal section taken on the line 5-5 of Fig. 1.

Fig. 6 is a, front view of the skip hoisting gear.

Referring by numerals tothe accompanying drawing which illustrates a preferred embodiment of my invention, I0 designates the incinerator body usually formed of concrete, brick, Vsheet metal or the like and having a charging opening ll generally located a substantial distance above the base of the incinerator body in order to provide a combustion chamber` of ample proportions below said charging opening.

Secured on the outer face of the incinerator body to the sides of the opening |I are vertically disposed parallel angle bars l2 which serve as tracks for the rollers of the skip or charging receptacle and immediately to the sides of opening |I, these bars are provided with outwardly pro- .iecting plates 3 which function as wind shields.

Arranged to slide freely between the inner portions of plates I3 is a metal door I4 which normally closes the charging opening suitably secured to body l0 and projecting outwardly therefrom above opening Il is an arm |5,\in the outer end of which is mounted for operation, a groovedpulley I6. Y f V A l Suspended from the innerend portiony l5 is a hanger l1 in which is journalled for independent rotation three grooved pulleys |8, |9 and 20 (see Fig. 4). -1 i i The skip or charging 'receptacle is aboxlike member 2| preferably-formed of sheet! metal, open at both ends and provided on its `outer end with inwardly projecting iiange's`22. f

Mounted on the lower front carriersoi` the skip are rollers 23 which traversefthe rails V`|2 and the latter areprovidediat their lower Yends with stops |2a which limit the downward travel of said rollers and the skip. s g Mounted on top of the skip is a. hinged cover 24 of wire netting or the like. Arranged4 to slide lengthwise Within the skip is an L-shaped mem-` ber 25, the upright portion of which serves as a closure for the outer end of the'skip, and when the skip is loaded and said member is drawn forwardly therethrough, the contents of said skip will be discharged from the forward end thereof.

Formed in the bottom of the skip is a longitudinally disposed groove 26 for the accommodation of a cable 21, one end of which is connected to the base of mem-ber 25 and the opposite end portion passing over a pulley 28 which is journalled in the forward end of the bottom of the skip, with a portion of said cable depending from said skip. This cable provides means for pulling member 25 forwardly through the skip when discharging the contents Vthereof through opening Il into the incinerator.

Mounted on the lower portion of the incinerator body are brackets 29 in which are mounted for rotation a drum 30 and a smaller drum 3|, with a shaft 32 journalled for rotation between said drums.

A gear wheel 33 on shaft 32 engages pinions 34 and 35 on drums 30 and 3| respectively, and on one end of said shaft 32, is mounted a crank handle 36. Shaft 32 carries a ratchet wheel 31 which is engaged by a pawl 38 on the adjacent bracket 29, thus providing means for holding the skip when elevated to discharging position.

Branches 39 of a cable 40 are connected to the rear upper corners of skip |2 and said cable extends upward over pulley IE thence toward. the in- ;nerator over pulley 20 and thence down to drum Branches 4| of a cable 42 are connected to the iront upper corners of the skip and said cable extends upward, thence over pulley I8 and thence downward to the small drum 3 I.

A cable 43 has one end connected to the upper end of door I4 and extends therefrom upward over pulley I9 and thence downward through a xed loop or ring 44 to a point above the skip actuating gear.

In the use of my improved incinerator, the skip in its lowermost position is filled with refuse and the coverv 24 closedthus preventing lighter parts of the load such alsv` paper andleaves from `being blown away by the wind.

Previous to the loading of the skip, member 25 is moved to the rear end thereof against flange 22, thus forming a rear wall for the receptacle.-

While being loaded the skip may' occupy a sub.

feed all of the refuse from said skip through opening I I into the incinerator.

While the skip is elevated as just described it is so held by the ratchet and pawl associated with crank shaft 32. The windshield I3 prevents paper, leaves and other lightweight refuse from being blown out of the forward portion of the skip while in load discharging position.

,After the charging operation as just described has been accomplished,` the skip is lowered to its normal position and member 25 is returned to the rear end of said skip and thus the latter is ready Y to be reloaded.

stantially horizontal position or an inclined posi'- tion with its rear end lower than its forward end.`

After being filled, the skip is elevated by actuating vcrank 32, which through gear 33 and pinions 34 and 3Y5 rotates drums; 30 and 3| .thereby winding cables 40, and 42'respectively thereon. l During this elevation of the skpzthe rollers-:23 traverse therails I2 and due to the difference in the sizes. of, drumsi-3ll and 3l, cable 48 `winding onto thelarge drum 30 will travel faster than cable 42 attached to the forward end of the skip sof that, as itmoves upward, the skip will be tiltedqwith its` rear end higher` than its forward end, as the latter is brought into position opposite the charging opening II. l

Cable 43 is now pulled down to elevate door I4 afterv which cable 21 is pulled down to' movemember 25 forwardly through the skip` ,and thereby Thus it will be seen that I have provided an incinerator which is simple in structure, inexpensive :of manufacture and verv effective in performing the functions for which it is intended.

' It will be understood that minor changes in the size, form and construction of my improved incineratorv may be made and substituted for thosey herein shown and described without departing from the spirit of the invention, the scope of whichis set forth in the appended claim;`

I claim as my invention:V In a hoist for delivering materiall to an elevated opening, a skip open at both ends, an L-shaped member arranged to slide lengthwise within said skip, which member when at its rearward limit of movement closes the rear end of saidskip.-k a flexible member secured to the forward end o f--said sliding member and extending lengthwisethrough said skip for drawing said member tothe forward end of said skip and a hinged cover for said jskipiA INOCENTE TREVINOU
